Design of a Framework for Security Enhancement in Telematics Control Units (TCUs)

摘要

Cars are increasingly being equipped with a variety of driver convenience and safety features, with many vehicles evolving into what are now called "smart" cars. The convenience and safety systems built into these vehicles, which include infotainment, connected car, and autonomous navigation systems, are being actively developed by combining them with mobile communication technology. However, utilizing such technology can potentially leak personal, or vehicle information. A mobile communication module for example, can be used to attack the electronic control device of a vehicle; the attacker then has the ability to endanger the driver by gaining control of the vehicle brakes and steering devices. To protect the driver and the vehicle from such risks, we have designed a technology that creates a secure zone for the storage of important information, restricting external access to the telematics control unit.
